Before there are too many routes to select in TSW2, I feel that it would be good to get ahead of the route selection list and provide a method of filtering routes, at least by region. It may be even more prudent to allow several filters and sorting methods so that players can find the routes that they are looking for more easily. If we have numerous dozens of routes in the future, managing what we want to drive may be difficult without this feature.
